To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild_questions@onsemi.com.

Description
The FMS6404 is a single composite video 5th-order Butterworth low-pass video filter optimized for minimum overshoot and flat group dela y. The device contains an audio trap that removes video information in a spectral location of the subsequent RF audio carrier. The group delay compensation circuit pre-distorts the signal to compensate for the inhere nt receiver intermediate frequency (IF) filter’s group delay distortion. In a typical application, the composite video from the DAC is AC coupled into the filter. The CV input has DC- restore circuitry to clamp the DC input levels during video synchronization. The clamp pulse is derived from the CV channel. All outputs are capable of driving 2V PP, AC- or DC- coupled, into either a single or dual video load. A single video load consists of a series 75 Ω impedance matching resistor connected to a terminated 75 Ω line. This presents a total of 150 Ω of loading to the part. A dual load would be two of these in parallel, which presents a total of 75 Ω to the part. The gain of the CV signal is 6dB with 1V PP input levels. All video channels are clamped during synchronization to establish the appropriate output voltage reference levels.
